Claims.

It is a further object of my invention to form the parts so that the firm holding of the movable head may be accomplished without the use of separate springs.

Another object of my invention is to provide an improved cufi link construction having a small number of parts which may be readily manufactured and assembled at a low factory cost.

With the above and other objects and advantageous features in View, my invention consists of a novel arrangement of parts more fully disclosed in the detailed description following, in conjunction with the accompanying drawing, and more specifically defined in the claims appended thereto.

In the drawing:

Fig. 1 is an elevation of the novel cuIf link;

Fig. 2 is a side View thereof;

Fig. 3 is a section on the line 3-3 of Fig. 2;

Fig. 4 is a perspective view of one arm, the relative positions of the movable head with respect thereto being shown in dotted lines;

Fig.5 is a side elevation of one arm;

Fig. 6 is a perspective view of the movable head, showing one of the pivot recesses; and

Fig. 7 is an enlarged fragmentary sectional detail view taken along line l--! of Fig. 1.

It has been found desirable to provide a cuff link construction having a movable head, in which the parts are so designed that no separate springs or cam parts are required for retaining the movable head in selected position. To this 'end I have devised a link body having two sides disposed in spaced, generally parallel relation, these arms having cam portions formed therein, and I have positioned a movable head between these sides so as to releasably lockingly engage the cam portions of the sides when moved in a position parallel to or perpendicular to the body of the link. I have further formed the sides so as to permit nesting of the movable head therein when it is positioned between said sides.

Referring to the drawing, the novel cuif link It! includes a body portion l l and a movable head ii, the body portion II consisting of two sides l3, M which have their lower ends retained in an elongated tubular socket I5, which prevents rockin-g movement of said sides and which is preferably open at the base togive greater resiliency and facilitate the insertion of the lower ends of the sides !3 and M. The lower ends of the sides l3 and l t extend'into said socket to a point short of the bottom, seeFig. 7. A fixed head 16 of any desired shape and design is rigidly attached to the socket [5 or formed integral therewith.

The two sides are both alike, except that they are oppositely formed; one side i3, is shown in perspective in Fig. 4, and has a lower base portion l! and an offset upper portion l8,'the lower base portion being indented or otherwise recessed or scored as indicated at I9, see Fig. 5, to permit a firm grip of the retaining socket I5 when the parts are assembled. The upper portion I8 is rounded on the exterior as indicated at 20 in 5, and has a flat central portion 21 and two longitudinal edge ridges 22 which terminate adjacent theupper end of the side in curved or arouate tips 23 which form. a cam seat for the movable head, the adjacent sides of the two ridges 22 and the central flat portion forming a cam recess for nestingly receiving one end of the movable head, as hereinafter explained. As best shown in Fig. 4, the upper end of the side and the upper seat tips 23 of the ridges are circular arcs, and a pivot pin 24 is positioned centrally between the tips and the upper end and projects laterally as shown in Fig. 5.

Referring now to generally torpedo-shape, as illustrated, and has two aligned centrally disposed openings 25 on opposite sides thereof for receiving the pivot pins 24 of the sides [3 and It. The curvature of the central portion of the movable head corresponds to the tip curvature, and the sides of the movable head and the recess also correspond. When the parts are assembled, the socket l5 firmly grips the lower ends of the two sides, and the movable head, when positioned as shown in Fig. l, snugly fits against the cam tips 23, the resilience of the sides releasably locking the movable head in this position, and the pivot pins 24 eifectively preventing any separation of the movable head from the sides during turning movement. When the movable head is turned to the parallel position shown in dotted lines in Fig. 4, the movable head engages the tips 23 and ridges 22 and spreads the two sides apart and then snaps into the recess formed by the adjacent edges of the two ridges Fig. 6, the movable. head is 7541 and the flat portion 2|, whereby the parts are again releasably locked together.

The improved link construction thus comprises two sides which have ridges formed so as to provide seats for the movable head in two positions, either at right angles to or parallel to the body of the link, and which are moved slightly apart when turning the movable head and then snapped together to lock the movable head in the other position, the arms being provided with pivot pins 24 which seat deeply into aligned openings in the movable head so that the movable head cannot be inadvertently or accidentally withdrawn or released from its seating engagements. The parts are preferably made of stamped metal, ornamented as desired.

While I have described a specific constructional embodiment of my invention, it is obvious that changes in the size and shape of the parts and in the manner of assembly, may be made to suit different requirements for ornamental cuff links, without departing from the spirit and the scope of the invention as defined in the appended claims.

I claim:

1. In a cuff link, a shank arrangement having two spaced sides, said sides having aligned pivot means projecting inwardly therefrom adjacent one end thereof, and a movable head having aligned openings receiving said pivot means, said sides having spaced cam means forming a recess therebetween, said head being adapted to nest in said recess when in alignment with said shank, said spaced cam means releasably locking said head in nested position.

2. In a cuff link, a shank arrangement having two spaced sides, said sides having aligned pivot means projecting inwardly therefrom adjacent one end thereof, and a movable head having aligned openings receiving said pivot means, each of said sides having spaced cam means extending in alignment with said shank and terminating in cam seats adjacent said pivot means, said head being adapted to releasably engage said cam seats when at right angles to said shank and to nest between said spaced cam means when in alignment with said shank.

3. In a cuff link, a shank arrangement having two spaced resilient sides, said sides having aligned pivot means projecting inwardly therefrom adjacent one end thereof, and a movable head having aligned openings receiving said pivot means, said sides being recessed and said head being shaped to nest Within said recesses in alignment with said shank whereby said head is releasably locked in said shank by the resiliency of said sides.

4. In a cuff link, a shank arrangement having tWo spaced sides, said sides having aligned pivot pins projecting inwardly therefrom adjacent one end thereof, a movable head having aligned openings receiving said pivot pins, and means on said sides adjacent said pivot pins adapted to engage the surface of said head for releasably locking said head at right angles to said shank, said sides being recessed to the shape of said head to releasably lock said head in nested engagement therewith in alignment with said shank.

5. In a cuff link, a shank arrangement having two spaced sides, said sides having aligned pivot pins projecting inwardly therefrom adjacent one end thereof, and a movable head having aligned openings receiving said pivot pins, said sides having spaced ridges with cam seats adjacent said pins, said head being shaped to engage said cam seats to releasably seat thereon at right angles to said shank.
